Opinion:
In 1998 (updated in 2002), professors Edward S. Herman and Noam Chomsky wrote the seminal book, Manufacturing Consent: The Political Economy of the Mass Media, to explain how propaganda and prejudices function in our mass media. They described a "propaganda model" without a conspiratorial bent or monolithic government control. They suggested the use of several "filters" that help determine the media - 1) ownership of the media; 2) the media's funding sources/advertising; 3) sourcing; 4) flak; and 5) "fear ideology" (such as fear of immigrants).
To be clear, this model has nothing to do with the often-unhinged "fake media" accusations by the far right. These claims of mainstream media fabrication are generally diversions. The extreme right's purpose is often to take the attention away from their own politically motivated fabrications such as Trump's "stolen election" or anti-vaccine/masking misinformation. The internet has made this phenomenon worse by masking identities and atomising people into tribal factions.
Although consent by a majority may be "manufactured" by spin doctors, outright manufactured news in the mainstream is rare. Exceptions include the media overplay of the 2003 Saddam statue-toppling in Iraq by the US, later exposed in the same media as a staged propaganda ploy by the US military.
The most common method of mystifying the media is framing the news with clear prejudice, and "flak" (as in WWII anti-aircraft explosions in the sky used as diversions) as a means of disciplining the media by flooding them with negative responses to a media statement or programme. "It is produced on a large scale, or by individuals or groups with substantial resources." Two decades ago, Frank Luntz, an American political and communications consultant for the Republican Party reframed the phrase "global warming" to the more benign "climate change". This phrase became the new media catchword.
